Sleep Chamber is an American industrial band fronted by John Zewizz. The band is known for using S&M, bondage and magic imagery on their artwork, during their performances, and within their lyrics. Formed in 1981 by high school friends Zewizz, Eugene Difrancisco, and Phil Brosseau, over the years the Sleep Chamber lineup has changed many times with Zewizz being the sole permanent member. Previous members of Sleep Chamber have included Thomas Thorn, Michael Moynihan, Jonathan Briley and Elaine Walker. Since the beginning, Zewizz has stated that the constant lineup changes are because Sleep Chamber is not a "band", but rather a "concept". From 1982 to 1999, Sleep Chamber put out a considerable volume of music (releasing over 70 recordings, and participating in over 35 various artists releases). After an extended absence, Sleep Chamber returned in 2008 with a new lineup, a slew of new releases, and a revised name, SLEEPCHAMBER. 1981–1990 Difrancisco and Brosseau had fronted a band called The Product; Zewizz produced their sole single. When The Product folded, Difrancisco and Brosseau began a band called Daze of Trance. Zewizz occasionally helped out with Daze of Trance, even playing on a cassette release as part of the band. Sometime between 1981 and 1982, Sleep Chamber came into existence, with Zewizz as the frontman. Their earliest works were experimental and electronic/industrial in nature. Live Sleep Chamber performances were quickly labeled as resembling a "Black Mass", with smoke (containing a special blend of incense) billowing out of machines, and the band donning black bondage masks while performing on stage. Their concerts scared some local club owners, prompting them to ban Sleep Chamber from playing. Local reviewers often accused the band of being Satanic. Zewizz, over the years, has denied this accusation. Those early concerts featured Zewizz in different combinations with Difrancisco, Brosseau, Thorn, Moynihan and also Malcom Smith (with whom Zewizz collaborated in the bands Dokument and Hidious in Strength), Darlene Victor, and Richard Gellar. 1990–2001, Sleep Chamber and The Barbichuettes During the 1990s, Zewizz incorporated bondage-fetish dancers called The Barbitchuettes into Sleep Chamber's live performances. With this addition, the band's popularity exploded. During live shows, the Barbitchuette dancers would perform Fetish and S&M acts on the stage as well as caress and dance with other Barbitchuettes. During the Barbitchuettes heyday with Sleep Chamber, it was not uncommon for the band to travel with up to 11 Barbitchuette dancers. Zewizz also
